“…Several researchers still use the same technique to study the electrical behaviour of molecules incorporated in a LB film. In recent years, a large variety of conceptually new junctions have been designed to measure the current densities through a single molecule or few molecules within a SAM, including STM (Han 1997;Bumm et al 1999;Zeng et al 2002;Monnell et al 2005;Haiss et al 2006;Weiss et al 1998), conducting AFM (cAFM; Kelley et al 1999;Leatherman 1999;Wold & Frisbie 2000;Beebe et al 2002;Cui 2002a;Rawlett et al 2002;Wold et al 2002;Ramachandran 2003;Engelkes et al 2004;Engelkes et al 2005), gold nanoparticle-mediated cAFM (Cui 2001(Cui , 2002b, nanopore (Zhou et al 1997;Chen et al 1999;Lee et al 2003a;Wang et al 2003a,b), crosswire (Blum 2005) and in-wire junctions (Kratochvilova et al 2002a;Blum et al 2004). Each type of junction has specific advantages and disadvantages with respect to fabrication, reproducibility and application.…”

In this paper, we discuss the current state of organic and molecular-scale electronics, some experimental methods used to characterize charge transport through molecular junctions and some theoretical models (superexchange and barrier tunnelling models) used to explain experimental results. Junctions incorporating self-assembled monolayers of organic molecules-and, in particular, junctions with mercury-drop electrodes-are described in detail, as are the issues of irreproducibility associated with such junctions (due, in part, to defects at the metal-molecule interface).

“…The DNA molecule, containing the genetic code of all living species, has recently become a center of great attention on the part of chemists and physicists, one of the reasons being DNA's potential use in nanoelectronic devices [1][2][3][4], both as a template for assembling nanocircuits and as an active element of such circuits. Charge migration along DNA molecules has attracted scientific interest for more than fifty years.…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractThe conductivity of DNA covalently bonded to a gold surface was studied by means of the STM technique. Various single-and double-stranded 32-nucleotide-long DNA sequences were measured under ambient conditions so as to provide a better understanding of the complex process of chargecarrier transport in natural as well as chemically modified DNA molecules. The investigations focused on the role of several features of DNA structure, namely the role of the negative charge at the backbone phosphate group and the related complex effects of counterions, and of the stacking interactions between the bases in Watson-Crick and other types of base pairs. The measurements have indicated that the best conductor is DNA in its biologically most relevant double-stranded form with Watson-Crick base pairs and charged phosphates equilibrated with counterions and water. All the studied modifications, including DNA with non-Watson-Crick base pairs, the abasic form, and especially the form with phosphate charges eliminated by chemical modifications, lower the conductivity of natural DNA.

“…TD‐DFT is an extension of DFT determined to investigate excited states and non‐equilibrium properties of many‐body systems in the presence of time‐dependent potentials. This method enables the analysis of the character and localization of individual excited states 23–25. Zyubin et al 18 used TD‐DFT for the analysis of optical properties of approximately 100 atoms containing ND particles with neutral and negatively charged vacancy‐related ND point defects (N 2 V 0 , N 2 V − , and N 3 V 0 ).…”

In this article, theoretical interpretation and prediction of the optical properties of nanodiamond (ND) particles', containing various luminescence centers, was made. Particularly, nitrogen, and chromium atoms embedded into the diamond crystal lattice were modeled. In the case of nitrogen centers containing ND particles, the effect of various surface terminations (hydrogen and/or oxygen, fluorine) was also studied. To get a qualitative better understanding of the complicated and specific process of ND particles, luminescence using density functional theory, were modeled processes and states influencing the luminescence of ND particles.
